A building specification from mid-3rd century BC Philadelphia in the Fayum setting out how a contractor is to lay the mosaic floors of a bath-house. It describes the women's rotunda floor, with a black border, a spiral shell motif, another band and a central poppy, the rest filled with pebbles, and orders similar work in the vestibule by the men's rotunda.
In English machine translation
[…] a painted (?) flower of one cubit on every side;
[there will be given] to the contractor […]
[…] from the royal (office?) a model
[according to] which it must be made ⟦which the contractor will make⟧; the
[rest] he will plaster with pebbles of six-choinix size.
Of the women's rotunda (tholos) the floor
he will make laid (in mosaic), keeping a distance from the
bathtubs of 1 cubit and
[2] palms, and he will put round it a black band
having a width of 2 fingers,
and he will also lay a nautical shell (spiral)
having a width of 10 fingers
[and] one band, whichever may suit,
[and] in the middle a poppy measuring in every direction
1 cubit; and the rest he will plaster with pebbles
of six-choinix size. He will also lay
in the vestibule the (floor) next to the
men's [rotunda] on the same terms.
The remaining floors, being plastered,
he will agree […]
[…]
[…]
The tholos is the circular bathing room of a Greek bath; 'six-choinix pebbles' apparently refers to a grade of pebble measured by the choinix, a dry measure. The 'nautical shell' (kochlos) is probably a spiral wave or shell pattern.
